John 14:15-17

John 14:15-17. If ye love me, keep my commandments. And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him:

The world is carnal, it is unspiritual; therefore, it is unable to see or to know the Spirit of God. A man without a spiritual nature cannot recognize the Holy Spirit; he must be born again before he can do so. You who are only soul and body need to receive that third and loftier principle - the spirit which is wrought in us by the Spirit of God. Until you have it, this verse applies to you: "The Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him."
